SPECIFICATION forming part of Letters Patent No. 484,044, dated October 11, 1892.

Application led April17, 1891. Serial No. 389,314. (Model.)

To all whom it may concern.-

Beit known that I, WILLIAM PENBERTHY, a citizen of the United States, residing at Leadville, in the county of Lake and State of Oolorado, have invented certain new andl useful Improvements in Automatic Restarting-Injectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention has relation to improvements in restarting-injectors for feeding steam-boilers; and the novelty will be fully understood from the following description and claims, when taken in connection with the accompanying drawings, in which- Figure l is a longitudinal sectional view of my improved restarting-injector, and Fig. 2 is a detail sectional view illustrating a modified form of relief-valve.

Referring byletters and gures to said drawings, A indicates the main casing or tubular section of my improvedinjector, which is provided with three laterally-proj ectin g branches ot, b, and c, the branch a leading from said main casing adjacent to the upper end thereof and having in practice suitable connection by a separable section with a water -tank or other source of supply. The branch or arm b projects from one side of the main casing and connects the intermediate and overflow water-chambers, a communication between said chambers being effected by overcoming the relief-valve, which normally rests between the same.

Projecting from the side of the casing, preferably opposite to the branch b, is another branch c, which leads from the overflow-chamber and is provided with an overiiow-valve, as will be presently described.

Suitably connected in a separable manner to the lower end of the casing or tubular sec- 4tion A is a feed-pipe B, which leads to the The main casing or tubular section Acorn prises three chambers C, D, and E, formed by the division-walls l and 2, and the upper of these chambers, which I shall denominate a vacuum-chamber and which is indicated into the chamber C to about midway the height thereof. i The lower end of the jet-section F, which is preferably beveled, as shown, discharges into the upper end of a suctionjet section G, a small space being allowed between said sections, whereby a vacuum may be created in the chamber O when the steam has been turned on.

The suction-jet G, which rests in the upper partition-wall, ispreferably secured in said wall by screw-threads, as shown, and its lower end extends down into the intermediate chamber D, where it. discharges into the upper end of the combining-tube, presently to be described, which extends up to within a slight distance of said jet-section.

Y Secured by a hinge to the casing A, adja cent to the upper horizontal partition-wall thereof, is a disk relief-valve H, which may be of any approved construction and is designed and adapted to normally close communication between the intermediate and overflow chambers. The seat of said valve H is arranged on a nearly-vertical plane, so that the valve when seated will readily open to a slight pressure in chamber D.

In Fig. 2 of the drawings I have illustrated a modified form of relief-valve constituted by a ball H', which may be of any suitable material, and this ball-valve, which is guided-in an inwardly-directed angular iange of a' socket-nut Hvnormally rests upon a seat afforded by the partitions l and 2, the latter being curved upwardly for that purpose. Said socket-nut is arranged at such an angle in relation to the main casing that the flanges will ICO gether with said pipe, by the lower-collar-nuv as shown. This combining-tube, whichis shouldered at points adjacent; to its' ends, whereby it is held in position, is provided with alongitudinal bore, as shown, which increases ind'iam'etler-from: its lower to its upper end, andi-formed ini the wall of saidv combiningtube at' about the elevation. illustrated isH a loler J?, which is`l designed to carry off theiwa'- terontstarting: the' injector, the water'ceasing' j to* flowy throughzsaidvhole ,when a'sufticientvelocit-yhasl'been attained to carry it on through theetube' to the pipe leading" tothe boiler,

when the overflow-valve will immediately settlein itsfnormal positionandprevent anyair from being carried in andventering the hole J.`

Secured-by screw-threads or the-like inthe branch.cwhich leads from theoverflow-chame ber E, is a socket-nut K, which is provided: withanr` inwardly-directed annular flange,Vv

which servesto seat aball-valve L, whichrests against the wall ofthe opening'and. servesto-l normally close communication between the valves L and H may escape'and perm-it ther valves to return back intol the socket. The' diaphragm?, is made thin to bef slightlyelas-v The` combiningetube is formed with a tic. shoulder N, bearing against the diaphragm-2. The discharge-tube has a shoulder P, adapted to bear against a corresponding shoulderk on: the casing. The diaphragmbeingmade elastic, when thev tube isforced againstsaid ,j

diaphragm (in placing the partsin. position) bythe tail-nutO a; tight jointwill b'e-nuade at P.

In the*y operation of myimprovedrestartingf' injector when steam has been admit-ted. into l the j et-pipe F and passes through the tapered the suction-jet produces avacuum in the'up- ,E per chamber, and when the Wat-er arri-ves atI The inWardly-directed-f that point .the swinging., or relief valve imme- ,A diately" falls andthe wateris conducted'down through the suction-jet and into the combining-tube, and from thence through the hole J and out through the overiow. When a sufficient velocity has been. attained, the water `ceasesV to ii'owthrough theA hole J and passes on to the boiler, and the overflow-valve, as bejfore described, dropsinto its seat at the same time the hinge-valve closes, thus preventing vair from being carried into the injector.

Fromthel foregoing description it will be seen that my improved injector is operated "by'a jet of' steam, which, after establishing the flow or current of water in the manner described, is discharged'f'rom` the injector andv passesA on to thel boiler.:

Having described' my invention, what I1 claim, and desire -to' secure by: Letters Patent, `1S-.

1. In an injector, the combination,.witl1;suc tion-tube G-andcham'ber D, formed by'walls l and 2, of the disk valve II, hinged. andarranged at an angle toy the vertical casing,.as' shown` and described.

2. In an injector, the combination, with suc-- tion-tube Gand chamber D, of the ball-valve II and' the flanged socket-nutzHz, arranged' *atA an angle to thercas-ing, asshown and de scribed.

3. In combinationA with the overflow o'f`an injector, the ball-valve-L and flanged socketnutiK, arranged` at an angle to the vertical casing, as shown and described.

4. In combination with tube Gr,.chamberD combining-tube I, chamber E, connecting `chamber D with the overflow, the disk vallve H", andfball-v-alve L, and: iia-nged socket-nut K, arranged, asf-shown, inrelationto the vertical.
